Sewer District targets future extraneous water project
Lisa Kristoff
Rehabbing some lines and fixing known leaky services is topping the
near future project list at the Boothbay Harbor Sewer District.
District Superintendent Chris Higgins is meeting with Wright Pierce
Civil Engineering Services of Portland to discuss the available options
utilized. This is particularly important because many of the lines
requiring attention are on private property.
"We are going to have to do some number crunching to see what that
impact will be on the district's costs," said Higgins. "It may be less
costly for us to go in and do the work ourselves."
Higgins said that technically, leaky services are the homeowner's
responsibility, but it might behoove the district, while they are checking
out lines, to complete the work. Doing the work may prove less costly
overall than the cost being incurred by the impact of the leaky services
on the facility.
Higgins said each service on Atlantic Avenue would have to be
inspected. The video work completed in spring of 2006 revealed where clean
water is running into the service.
"What we will have to do is access their homes and put a camera through
the clean out or do a pressure test to see if it is leaking," Higgins
said. "I would prefer to have a visual so we can actually see what is
going on as a first step."
Pressure testing would then be the second step for those homes that
reveal problems. This is an involved process requiring digging two
holes.
"We don't have permission to do anything now - we will be discussing
strategies, educating folks on what is going on … I don't expect
anything will happen until next year," Higgins said.
Higgins has been considering creating a stakeholders group to get the
neighborhood involved in the process.
Since the video work was completed, the district has completed major
repairs/breaks that were on the Meadow, one in the mouth of Route 96 and
Conley's driveway, a leak on Bay Street - this in conjunction with a
leaking hydrant, Giles Place - an interceptor was offset by six inches.
The district plans to address an issue at the Catholic Church on the
corner of Atlantic Avenue and Lobster Cove Road.
The inflow and infiltration (I & I) and smoke testing done in 2007, led
to the identification of extraneous water sources, with the most
significant stemming from the Atlantic Avenue area.
"Services are old and so are the joints. We have to get a handle on
what we are up against before we can chart a course of action," said
Higgins.
It would be helpful to complete the video work this fall - or
spring.
If the district does not address these issues, it will tax the
system.
"We have extraneous water getting in that is not intended to be
treated. If we don't address it in the sewer system, and we pump it, we
have to treat it," Higgins said.
"Now you are looking at more capacity at the plant, building a bigger
plant - where are you going to get the biggest bang for your buck? I would
rather fix the problems and extend the life of this plant."
Homeowners, said Higgins, have to share some of the burden - it is
their line, it is part of maintaining their septic systems.
There are 20 miles of sewer line in Boothbay Harbor and almost another
20 from the main to the house.
"People are not going to be happy, but the type of repair we decide on
may be a 50-60 year repair, we will make it as easy as possible for
people, but we have to take care of the infrastructure," Higgins said.
Residents can be certain that whatever course of action the district
decides on, regarding the Atlantic Avenue water issue, they will receive
notification by mail.
Other Repair Work
At the footbridge station, the district uncovered an unknown problem.
Last month, while the district was addressing a plug, they discovered one
of the pumps and the discharge piping would have to be replaced. Work at
this station will be completed shortly. Higgins anticipates it will take
one day or less.
A new control panel is being installed in the Spruce Point station. The
old station, right near the salt water pool, has been camouflaged with
spruce trees that conceal, but permit access if and when it is
necessary.
